Die Gleitschicht der Hueftgelenkpfanne besteht vorzugsweise aus Titaniumnitrid mit einer Schichtdicke bis zu 5 mm und einer mittleren Rauheit kleiner 3 mm. Als schichttragende Metalle sind insbesondere sperrschichtbildende Reinmetalle wie Titanium, Tantal, Niobium, Zirkonium oder deren Legierungen sowie alle anderen ueblichen metallischen oder keramischen Implantatmaterialien einsetzbar. Die dem Knochen zugewandte Seite ist makrostrukturiert mit einer mittleren Rauheit bis 300 mm und besitzt eine diffusionshemmende bioaktive Schicht vorzugsweise aus Titaniumnitrid und/oder Titaniumoxid. Die erfindungsgemaesse Loesung wird als Endoprothese verwendet.The invention relates to a wear-resistant Hüftgelenkpfanne, which is anchored in one piece cementless and made of metal and / or ceramic. The sliding layer of the hip joint socket preferably consists of titanium nitride with a layer thickness of up to 5 mm and an average roughness of less than 3 mm. In particular, barrier-layer-forming pure metals such as titanium, tantalum, niobium, zirconium or their alloys and all other conventional metallic or ceramic implant materials can be used as layer-bearing metals. The bone-facing side is macrostructured with an average roughness of up to 300 mm and has a diffusion-inhibiting bioactive layer, preferably of titanium nitride and / or titanium oxide. The solution according to the invention is used as an endoprosthesis.
Description
Die Erfindung betrifft eine verschleißfeste Hüftgelenkpfanne, die einteilig zementfrei verankerbar ist und für die Verwendung als Endoprothese dient.The invention relates to a wear-resistant acetabulum, which is anchored in one piece cementless and serves for use as an endoprosthesis.
Die in der Chirurgie des Hüftgelenkes verwendeten Hüftgelenkpfannen bestehen aus Plaste, vorzugsweise Polyethylen oder Metall mit Polyethylenersatz oder Vollkeramik. Das für Hüftgelenkpfannen eingesetzte Polyethylen (DE-OS 3200340, CH-PS 48747) ist in seiner Kompaktheit relativ gut biokompatibel. Es zeigt sich aber, daß der Abrieb, verursacht durch die Einwirkung des Kugelkopfes, vom Körper schwer oder nicht resorbiert wird. Dadurch können Entzündungen hervorgerufen werden, die Reoperationen nach sich ziehen. Trotz des aufgebrachten Verankerungsprofils an der Gelenkpfanne aus Polyethylen (CH-P 648747) gelingt nur eine unzureichende Langzeitfixation.The acetabular cups used in the surgery of the hip joint consist of plastic, preferably polyethylene or metal with polyethylene substitute or all-ceramic. The polyethylene used for acetabular cups (DE-OS 3200340, CH-PS 48747) is relatively well biocompatible in its compactness. It turns out, however, that the abrasion caused by the action of the ball head, the body is difficult or not absorbed. This can cause inflammation that causes reoperations. Despite the applied anchoring profile on the acetabular cup made of polyethylene (CH-P 648747) only an insufficient long-term fixation succeeds.
Günstiger lassen sich Zweikomponentenhüftgelenkpfannen, bestehend aus Metall und Polyethyleneinsatz (DE-OS 231473) im Knochen formschlüssig verankern. Allerdings bleibt der Nachteil des Einsatzes von Polyethylen, wie vorher beschrieben, bestehen.Cheaper can be two-component acetabular cups, consisting of metal and polyethylene insert (DE-OS 231473) anchored in the form-fitting bone. However, the disadvantage of using polyethylene remains as previously described.
In AT-P 337885 wird ein implantierbarer künstlicher Gelenkersatz aus Keramik vorgeschlagen, wobei Kopf und Pfanne aus Keramik bestehen. Trotz der guten Biokompatibilität der Keramik, der Resorbierbarkeit des Abriebes und der günstigen Gleitpaarungen, bleiben wie bei allen auch vorher beschriebenen Systemen, die geometrisch bedingten Nachteile bestehen. Das sind insbesondere die großen Abmessungen der Gelenkpfannen im Verhältnis zur Beckenanatomie.In AT-P 337885 an implantable artificial joint replacement made of ceramic is proposed, wherein head and socket are made of ceramic. Despite the good biocompatibility of the ceramic, the absorbability of the abrasion and the favorable sliding pairings, as with all previously described systems, the geometric disadvantages persist. These are in particular the large dimensions of the joint sockets in relation to the pelvic anatomy.
Oftmals sind dadurch zusätzliche Operationen wie Beckenosteotomien nach CHIARI oder Pfannendachplastiken nach HARRIS zur sicheren Verankerung notwendig. Dysplasiehüften können mit den bisher angebotenen Lösungen nicht versorgt werden.Often, additional surgeries such as pelvic osteotomies according to CHIARI or acetabulum sculptures according to HARRIS are necessary for secure anchoring. Dysplasia scars can not be treated with the previously offered solutions.
Alle bisher vorgestellten Lösungen berücksichtigen in ungenügendem Maße die relativ hohe mechanische Verschleißbeanspruchung an der Reibfläche Kugelkopf/Pfanne.All previously presented solutions take insufficient account of the relatively high mechanical wear stress on the friction surface ball head / pan.
Ziel der Erfindung ist es, eine biokompatible universell ein setzbare H üftgeienkpfanne zu schaffen, die sich sicher nach bekannter Operationstechnik verankern läßt und eine lange Liegdauer garantiert.The aim of the invention is to provide a biocompatible universally a settable Hüftgeienkpfanne, which can be safely anchored by known surgical technique and guarantees a long Liegdauer.
Die Aufgabe der Erfindung besteht darin, eine biokompatible, hoch verschleißfeste, mit guten Gleiteigenschaften versehene, mechanisch stabile Hüftgelenkpfanne zu schaffen, die einen guten Knochenkontakt ausbildet. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Gleitfläche der aus Metall und/oder aus Keramik bestehenden Hüftgelenkpfanne mit einer dichten Verschleißschutzschicht und die dem Knochen zugewandte Außenseite mit einer diffusionshemmenden bioaktiven Schicht versehen ist.The object of the invention is to provide a biocompatible, highly wear-resistant, provided with good sliding properties, mechanically stable acetabulum, which forms a good bone contact. According to the invention the object is achieved in that the sliding surface of the existing metal and / or ceramic acetabulum with a dense protective layer and the bone facing the outside is provided with a diffusion-inhibiting bioactive layer.
Als schichttragende Metalle sind insbesondere sperrschichtbildende Reinmetalle wie Titanium, Tantal, Niobium, Zirkonium und deren Legierungen sowie alle anderen metallischen oder keramischen Implantatmaterialien einsetzbar.In particular, barrier-layer-forming pure metals such as titanium, tantalum, niobium, zirconium and their alloys as well as all other metallic or ceramic implant materials can be used as layer-bearing metals.
Die Gleitschicht der Hüftgelenkpfanne besteht vorzugsweise aus Titaniumnitrid mit einer Schichtdicke bis zu 5μνη und einer mittleren Rauheit kleiner 3/j.m.The sliding layer of the acetabular cup preferably consists of titanium nitride with a layer thickness of up to 5 μm and an average roughness of less than 3 μm
Es wurde gefunden, daß die dichte Verschleißschutzschicht insbesondere Titaniumnitrid ein hohes Adsorptionsvermögen gegenüber proteinhaitigen Flüssigkeiten wie Gelenkflüssigkeit, Blut u.a. aufweist und damit eine festhaftende stabile Flüssigkeitsschicht zwischen den Reibpartnern garantiert und dadurch eine Festkörperreibung stark minimiert ist.It has been found that the dense wear protection layer, in particular titanium nitride, has a high adsorption capacity against proteinaceous liquids such as synovial fluid, blood and the like. and thus guarantees a firmly adhering stable liquid layer between the Reibpartnern and thus a solid state friction is greatly minimized.
Weiterhin verhindert die Titaniumnitridschicht eine Diffusion von Metallionen in das Implantatbett.Furthermore, the titanium nitride layer prevents diffusion of metal ions into the implant bed.
Es wurde weiter gefunden, daß die bisher bekannten Materialien des Kugelkopfes der Endoprothese insbesondere aus Keramik oder Metall als Reibpartner Verwendung finden können.It was further found that the previously known materials of the ball head of the endoprosthesis can be used in particular of ceramic or metal as a friction partner.
Die Außenseite der Hüftgelenkpfanne ist makrostrukturiert mit einer mittleren Rauheit bis 300>m und besitzt eine diffusionshemmende bioaktive Schicht vorzugsweise aus Titaniumnitrid mit einer Schichtdicke bis 5μΐη und/oder einer Oxidschicht insbesondere aus Titaniumoxid mit einer Schichtdicke bis ΙΟμ,ιη.The outside of the acetabulum is macrostructured with an average roughness of up to 300> m and has a diffusion-inhibiting bioactive layer preferably of titanium nitride with a thickness up to 5μΐη and / or an oxide layer in particular of titanium oxide with a thickness up to ΙΟμ, ιη.
Die diffusionshemmende bioaktive Schicht kann auch eine Matrixinselstruktur aus Titaniumnitrid mit maximal 40% Titaniumoxid sein.The diffusion-inhibiting bioactive layer may also be a matrix island structure of titanium nitride with a maximum of 40% titanium oxide.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment.
Eine präzisionsumgeformte Hüftgeienkpfanne aus Reinsttitan mit einem Innendurchmesser von 32,03 mm und einer Materialstärke von 1,08 mm hat auf der Außenseite eine Makrostruktur von 250/xm mittlerer Rauheit und auf der gelappten Innenseite eine mittlere Rauheit von 1 μ,ιη.A precision-formed Hüftgeienpfpfanne of pure titanium with an inner diameter of 32.03 mm and a material thickness of 1.08 mm on the outside has a macrostructure of 250 / xm average roughness and on the lobed inside an average roughness of 1 μ, ιη.
Auf diesem Grundkörper ist allseitig eine Titannitridschicht mit einer Stärke von 5μτη aufgebracht. Auf der Außenseite ist die Titannitridmatrix mitTitaniumoxidinsein versehen, die 30% der Oberfläche bedecken.On this body a titanium nitride layer with a thickness of 5μτη is applied on all sides. On the outside, the titanium nitride matrix is provided with titanium oxide in which cover 30% of the surface.
Testuntersuchungen mit dieser Hüftgelenkpfanne in einem Simulator ergaben eine Standzeiterhöhung von 300% gegenüber der unbeschichteten Hüftgelenkpfanne.Tests with this acetabulum in a simulator resulted in an increase in lifespan of 300% compared to the uncoated acetabular cup.
